disabled input will not submit data.

Use the readonly attribute:

<input type="text" readonly />

Source here

You can write edittext.setInputType(0) if you want to show the edittext but not input any values

Approach 4 (this is extension of wild coder answer)

txtName.disabled=1     // 0 for enable

<input id="txtName">

can use simply like

     <input [(ngModel)]="model.name" disabled="disabled"

I got it like this way. so i prefer.

Use the CSS pointer-events:none on fields you want to "disable" (possibly together with a greyed background) which allows the POST action, like:

<input type="text" class="disable">

.disable{
pointer-events:none;
background:grey;
}

Ref: https://developer.mozilla.org/en-US/docs/Web/CSS/pointer-events

This was the only code that worked for me:

element.removeProp('disabled')

Note that it's removeProp and not removeAttr.

I'm using jQuery 2.1.3 here.

*Updated

jQuery version would be something like below:

function load(recieving_id){
    $('#roommate_but').prop('disabled', true);
    $.get('include.inc.php?i=' + recieving_id, function(data) {
        $("#roommate_but").html(data);
    });
}

<select id="test" name="sel">
  <option disabled>1</option>
  <option disabled>2</option>
</select>   

or you can use jQuery

$("#test option:not(:selected)").prop("disabled", true);

In addition to other replies. If you allow html in options you can pass jQuery object to content, and it will be appended to popover's content with all events and bindings. Here is the logic from source code:

• if you pass a function it will be called to unwrap content data
• if html is not allowed content data will be applied as text
• if html allowed and content data is string it will be applied as html
• otherwise content data will be appended to popover's content container

$("#popover-button").popover({
    content: $("#popover-content"),
    html: true,
    title: "Popover title"
});

For MAC user, add this line into your Default Settings

File path is: /Users/USER_NAME/Library/Application Support/Code/User/settings.json

"tslint.autoFixOnSave": true

Sample of the file would be:

{
    "window.zoomLevel": 0,
    "workbench.iconTheme": "vscode-icons",
    "typescript.check.tscVersion": false,
    "vsicons.projectDetection.disableDetect": true,
    "typescript.updateImportsOnFileMove.enabled": "always",
    "eslint.autoFixOnSave": true,
    "tslint.autoFixOnSave": true
}

Whilst agreeing with Douwe Maan and Erik's answers, there are a couple of other things here that you may find useful.

Firstly, within your head tags, you can reference a separate JavaScript file, which is then reusable:

<script language="JavaScript" src="/common/common.js"></script>

where common.js is your reusable function file in a top-level directory called common.

Secondly, you can delay the operation of a script using setTimeout, e.g.:

setTimeout(someFunction, 5000);

The second argument is in milliseconds. I mention this, because you appear to be trying to delay something in your original code snippet.

After googling I write a simple Exception handing based on MVC Action Filter:

public class HandleExceptionAttribute : HandleErrorAttribute
{
    public override void OnException(ExceptionContext filterContext)
    {
        if (filterContext.HttpContext.Request.IsAjaxRequest() && filterContext.Exception != null)
        {
            filterContext.HttpContext.Response.StatusCode = (int)HttpStatusCode.InternalServerError;
            filterContext.Result = new JsonResult
            {
                JsonRequestBehavior = JsonRequestBehavior.AllowGet,
                Data = new
                {
                    filterContext.Exception.Message,
                    filterContext.Exception.StackTrace
                }
            };
            filterContext.ExceptionHandled = true;
        }
        else
        {
            base.OnException(filterContext);
        }
    }
}

and write in global.ascx:

 public static void RegisterGlobalFilters(GlobalFilterCollection filters)
 {
      filters.Add(new HandleExceptionAttribute());
 }

and then write this script on the layout or Master page:

<script type="text/javascript">
      $(document).ajaxError(function (e, jqxhr, settings, exception) {
                       e.stopPropagation();
                       if (jqxhr != null)
                           alert(jqxhr.responseText);
                     });
</script>

Finally you should turn on custom error. and then enjoy it :)

I wasn't happy with any of the awk solutions presented here because I wanted to extract the first few columns and then print the rest, so I turned to perl instead. The following code extracts the first two columns, and displays the rest as is:

echo -e "a  b  c  d\te\t\tf g" | \
  perl -ne 'my @f = split /\s+/, $_, 3; printf "first: %s second: %s rest: %s", @f;'

The advantage compared to the perl solution from Chris Koknat is that really only the first n elements are split off from the input string; the rest of the string isn't split at all and therefor stays completely intact. My example demonstrates this with a mix of spaces and tabs.

To change the amount of columns that should be extracted, replace the 3 in the example with n+1.

You can use below command if you want to print entire line and file name if the occurrence of particular word in current directory you are searching.

grep -m 1 -r "Not caching" * | head -1

For React.js, you can do this with more readable code. Hope it helps.

handleCheckboxChange(e) {
  console.log('value of checkbox : ', e.target.checked);
}
render() {
  return <input type="checkbox" onChange={this.handleCheckboxChange.bind(this)} />
}

The text uses combining characters, also known as combining marks. See section 2.11 of Combining Characters in the Unicode Standard (PDF).

In Unicode, character rendering does not use a simple character cell model where each glyph fits into a box with given height. Combining marks may be rendered above, below, or inside a base character

So you can easily construct a character sequence, consisting of a base character and “combining above” marks, of any length, to reach any desired visual height, assuming that the rendering software conforms to the Unicode rendering model. Such a sequence has no meaning of course, and even a monkey could produce it (e.g., given a keyboard with suitable driver).

And you can mix “combining above” and “combining below” marks.

The sample text in the question starts with:

• LATIN CAPITAL LETTER H - H
• COMBINING LATIN SMALL LETTER T - ͭ
• COMBINING GREEK KORONIS - ̓
• COMBINING COMMA ABOVE - ̓
• COMBINING DOT ABOVE - ̇

The first maximum you would hit is the length of a String which is 2³¹-1 digits. It's much smaller than the maximum of a BigInteger but IMHO it loses much of its value if it can't be printed.

I've been learning android for the last few months, so I'm far from an expert, but I've been really disappointed with the documentation on ANRs.

Most of the advice seems to be geared towards avoiding them or fixing them by blindly looking through your code, which is great, but I couldn't find anything on analyzing the trace.

There are three things you really need to look for with ANR logs.

1) Deadlocks: When a thread is in the WAIT state, you can look through the details to find who it's "heldby=". Most of the time, it'll be held by itself, but if it's held by another thread, that's likely to be a danger sign. Go look at that thread and see what it's held by. You might find a loop, which is a clear sign that something has gone wrong. This is pretty rare, but it's the first point because when it happens, it's a nightmare

2) Main thread Waiting: If your main thread is in the WAIT state, check if it's held by another thread. This shouldn't happen, because your UI thread shouldn't be held by a background thread.

Both of these scenarios, mean you need to rework your code significantly.

3) Heavy operations on the main thread: This is the most common cause of ANRs, but sometimes one of the harder to find and fix. Look at the main thread details. Scroll down the stack trace and until you see classes you recognize (from your app). Look at the methods in the trace and figure out if you're making network calls, db calls, etc. in these places.

Finally, and I apologize for shamelessly plugging my own code, you can use the python log analyzer I wrote at https://github.com/HarshEvilGeek/Android-Log-Analyzer This will go through your log files, open ANR files, find deadlocks, find waiting main threads, find uncaught exceptions in your agent logs and print it all out on the screen in a relatively easy to read manner. Read the ReadMe file (which I'm about to add) to learn how to use it. It's helped me a ton in the last week!

yourNode.Toggle(); //use that function on your node, it toggles it

Do not use $('title').text('hi'), because IE doesn't support it.

It is better to use document.title = 'new title';

http://dev.mysql.com/doc/refman/5.0/en/insert-select.html

For case1:

INSERT INTO TAB_STUDENT(name_student, id_teacher_fk)
SELECT 'Joe The Student', id_teacher
  FROM TAB_TEACHER
 WHERE name_teacher = 'Professor Jack'
 LIMIT 1

For case2 you just have to do 2 separate insert statements

I have this issue too. I suspect there is an issue with DigitalOcean’s nameservers, so this will likely affect a lot of other people too. Here’s what I’ve done to temporarily get around it - but someone else might be able to advise on a better long-term fix:

1. Make sure your DNS Resolver config file is writable:

   sudo chmod o+r /etc/resolv.conf

2. Temporarily change your DNS to use Google’s nameservers instead of DigitalOcean’s:

   sudo nano /etc/resolv.conf

Change the IP address in the file to: 8.8.8.8

Press CTRL + X to save the file.

This is only a temporary fix as this file is automatically written/updated by the server, however, I’ve not yet worked out what writes to it so that I can update it permanently.

Different ways:

1. Using SQL Server Agent (If local instance)
   schedule a job in sql server agent with a new step having type as "T-SQL" then run the job.

2. Using SQLCMD

I wanted a simple example of the use of case that I could play with, this doesn't even need a table. This returns odd or even depending whether seconds is odd or even

SELECT CASE MOD(SECOND(NOW()),2) WHEN 0 THEN 'odd' WHEN 1 THEN 'even' END;

From Symfony2 documentation: Absolute URLs for assets were introduced in Symfony 2.5.

If you need absolute URLs for assets, you can set the third argument (or the absolute argument) to true:

Example:

<img src="{{ asset('images/logo.png', absolute=true) }}" alt="Symfony!" />

When navigating between two separate directories and copying files back and forth, I do this:

cd /some/where/long
src=`pwd`
cd /other/where/long
dest=`pwd`

cp $src/foo $dest

command completion will work by expanding the variable, so you can use tab completion to specify a file you're working with.

Where possible, I prefer to call the function rather than dispatch an event. This works well if you have control over the code you want to run, but see below for cases where you don't own the code.

window.onresize = doALoadOfStuff;

function doALoadOfStuff() {
    //do a load of stuff
}

In this example, you can call the doALoadOfStuff function without dispatching an event.

In your modern browsers, you can trigger the event using:

window.dispatchEvent(new Event('resize'));

This doesn't work in Internet Explorer, where you'll have to do the longhand:

var resizeEvent = window.document.createEvent('UIEvents'); 
resizeEvent.initUIEvent('resize', true, false, window, 0); 
window.dispatchEvent(resizeEvent);

jQuery has the trigger method, which works like this:

$(window).trigger('resize');

And has the caveat:

Although .trigger() simulates an event activation, complete with a synthesized event object, it does not perfectly replicate a naturally-occurring event.

You can also simulate events on a specific element...

function simulateClick(id) {
  var event = new MouseEvent('click', {
    'view': window,
    'bubbles': true,
    'cancelable': true
  });

  var elem = document.getElementById(id); 

  return elem.dispatchEvent(event);
}

Though both @pkozlowski.opensource's and @Mark's answers are correct, I'd like to share my slightly modified version where I always select the first item in the list, regardless of its value:

<select ng-options="option.value as option.name for option in typeOptions" ng-init="form.type=typeOptions[0].value">
</select>

Faced this recently on XCode 7.3.1 - for me, I noticed RAM usage going to 100% on to CleanMyMac3. The problem magically fixed itself after I restarted my machine. In all fairness however, I'd already gone ahead and tried the accepted-answer, so you'll want to do the same before you restart just in case :-)

Since the name is likely to change in future versions of Android (currently the latest is AppCompatActivity but it will probably change at some point), I believe a good thing to have is a class Activity that extends AppCompatActivity and then all your activities extend from that one. If tomorrow, they change the name to AppCompatActivity2 for instance you will have to change it just in one place.

XCode2: sudo xcode-select -s /Applications/Xcode\ 2.app/Contents/Developer

Pay attention to the "\" to escape the space

This turns out to be a very interesting question. With over a hundred properties being set, you'd think that you'd be allowed to type .clickable { onclick : "alert('hi!');" ; } in your CSS, and it'd work. It's intuitive, it makes so much sense. This would be amazingly useful in monkey-patching dynamically-generated massive UIs.

The problem:
The CSS police, in their infinite wisdom, have drawn a Chinese wall between presentation and behavior. Any HTML properly labeled on-whatever is intentionally not supported by CSS. (Full Properties Table)

The best way around this is to use jQuery, which sets up an interpreted engine in the background to execute what you were trying to do with the CSS anyway. See this page: Add Javascript Onclick To .css File.

Good luck.

Reason of the error: Package name left blank while creating a class. This make use of default package. Thus causes this error.

Quick fix:

1. Create a package eg. helloWorld inside the src folder.
2. Move helloWorld.java file in that package. Just drag and drop on the package. Error should disappear.

Explanation:

• My Eclipse version: 2020-09 (4.17.0)
• My Java version: Java 15, 2020-09-15

Latest version of Eclipse required java11 or above. The module feature is introduced in java9 and onward. It was proposed in 2005 for Java7 but later suspended. Java is object oriented based. And module is the moduler approach which can be seen in language like C. It was harder to implement it, due to which it took long time for the release. Source: Understanding Java 9 Modules

When you create a new project in Eclipse then by default module feature is selected. And in Eclipse-2020-09-R, a pop-up appears which ask for creation of module-info.java file. If you select don't create then module-info.java will not create and your project will free from this issue.

Best practice is while crating project, after giving project name. Click on next button instead of finish. On next page at the bottom it ask for creation of module-info.java file. Select or deselect as per need.

If selected: (by default) click on finish button and give name for module. Now while creating a class don't forget to give package name. Whenever you create a class just give package name. Any name, just don't left it blank.

If deselect: No issue

When in doubt, read the documentation:

filename = "C:\Temp\vblist.txt"

Set fso = CreateObject("Scripting.FileSystemObject")
Set f = fso.OpenTextFile(filename)

Do Until f.AtEndOfStream
  WScript.Echo f.ReadLine
Loop

f.Close

The most simplist thing you can try is:

df=df[[ 'Mid',   'Upper',   'Lower', 'Net'  , 'Zsore']]

You have to start a service in your Application class to run it always. If you do that, your service will be always running. Even though user terminates your app from task manager or force stop your app, it will start running again.

Create a service:

public class YourService extends Service {

    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        // do your jobs here
        return super.onStartCommand(intent, flags, startId);
    }
}

Create an Application class and start your service:

public class App extends Application {

    @Override
    public void onCreate() {
        super.onCreate();

        startService(new Intent(this, YourService.class));
    }
}

Add "name" attribute into the "application" tag of your AndroidManifest.xml

android:name=".App"

Also, don't forget to add your service in the "application" tag of your AndroidManifest.xml

<service android:name=".YourService"/>

And also this permission request in the "manifest" tag (if API level 28 or higher):

<uses-permission android:name="android.permission.FOREGROUND_SERVICE"/>

UPDATE

After Android Oreo, Google introduced some background limitations. Therefore, this solution above won't work probably. When a user kills your app from task manager, Android System will kill your service as well. If you want to run a service which is always alive in the background. You have to run a foreground service with showing an ongoing notification. So, edit your service like below.

public class YourService extends Service {

    private static final int NOTIF_ID = 1;
    private static final String NOTIF_CHANNEL_ID = "Channel_Id";

    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId){

        // do your jobs here

        startForeground();
        
        return super.onStartCommand(intent, flags, startId);
    }

    private void startForeground() {
        Intent notificationIntent = new Intent(this, MainActivity.class);

        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0,
                notificationIntent, 0);

        startForeground(NOTIF_ID, new NotificationCompat.Builder(this, 
                NOTIF_CHANNEL_ID) // don't forget create a notification channel first
                .setOngoing(true)
                .setSmallIcon(R.drawable.ic_notification)
                .setContentTitle(getString(R.string.app_name))
                .setContentText("Service is running background")
                .setContentIntent(pendingIntent)
                .build());         
    }
}

EDIT: RESTRICTED OEMS

Unfortunately, some OEMs (Xiaomi, OnePlus, Samsung, Huawei etc.) restrict background operations due to provide longer battery life. There is no proper solution for these OEMs. Users need to allow some special permissions that are specific for OEMs or they need to add your app into whitelisted app list by device settings. You can find more detail information from https://dontkillmyapp.com/.

If background operations are an obligation for you, you need to explain it to your users why your feature is not working and how they can enable your feature by allowing those permissions. I suggest you to use AutoStarter library (https://github.com/judemanutd/AutoStarter) in order to redirect your users regarding permissions page easily from your app.

By the way, if you need to run some periodic work instead of having continuous background job. You better take a look WorkManager (https://developer.android.com/topic/libraries/architecture/workmanager)

if you add a jpg,png,pdf picture, you should use pdflatex to compile it.

If you're working with datatypes of fixed length, you can cast to binary to do this very easily and very quickly. Assuming DocumentId and DocumentSessionId are both ints, and are therefore 4 bytes long...

SELECT COUNT(DISTINCT CAST(DocumentId as binary(4)) + CAST(DocumentSessionId as binary(4)))
FROM DocumentOutputItems

My specific problem required me to divide a SUM by the COUNT of the distinct combination of various foreign keys and a date field, grouping by another foreign key and occasionally filtering by certain values or keys. The table is very large, and using a sub-query dramatically increased the query time. And due to the complexity, statistics simply wasn't a viable option. The CHECKSUM solution was also far too slow in its conversion, particularly as a result of the various data types, and I couldn't risk its unreliability.

However, using the above solution had virtually no increase on the query time (comparing with using simply the SUM), and should be completely reliable! It should be able to help others in a similar situation so I'm posting it here.

If you are using bootstrap.js then the below code might be useful. This is very simple. Dont have to write anything in js to invoke the pop-up.

This is how it works for me but might be different for you, I recommend to watch some Unity Tutorials on the Scripting API.

I use Bootstrap 3.4 For me this does not work

$('#myModal').modal('hide')

In desperation,I did this:

$('#myModal').hide();
$('.modal-backdrop').hide();

Maybe it's not elegant, but it works

Further extended the regex given by @AlokChaudhary to support:

1. dd mmm YYYY (in addition to dd-mmm-YYYY, dd/mmm/YYYY, dd.mmm.YYYY).

2. mmm in all CAPITAL LETTERS format (in addition to Title format)

dd mmm YYYY e.g. 30 Apr 2026 or 24 DEC 2028 are popular.

Extended regex:

(^(?:(?:(?:31(?:(?:([-.\/])(?:0?[13578]|1[02])\1)|(?:([-.\/ ])(?:Jan|JAN|Mar|MAR|May|MAY|Jul|JUL|Aug|AUG|Oct|OCT|Dec|DEC)\2)))|(?:(?:29|30)(?:(?:([-.\/])(?:0?[13-9]|1[0-2])\3)|(?:([-.\/ ])(?:Jan|JAN|Mar|MAR|Apr|APR|May|MAY|Jun|JUN|Jul|JUL|Aug|AUG|Sep|SEP|Oct|OCT|Nov|NOV|Dec|DEC)\4))))(?:(?:1[6-9]|[2-9]\d)?\d{2}))$|^(?:29(?:(?:([-.\/])(?:0?2)\5)|(?:([-.\/ ])(?:Feb|FEB)\6))(?:(?:1[6-9]|[2-9]\d)?(?:0[48]|[2468][048]|[13579][26])|(?:(?:16|[2468][048]|[3579][26])00)))$|^(?:(?:0?[1-9]|1\d|2[0-8])(?:(?:([-.\/])(?:(?:0?[1-9]|(?:1[0-2])))\7)|(?:([-.\/ ])(?:Jan|JAN|Feb|FEB|Mar|MAR|May|MAY|Jul|JUL|Aug|AUG|Oct|OCT|Dec|DEC)\8))(?:(?:1[6-9]|[2-9]\d)?\d{2}))$)

Test cases included in the Regex Demo

Features (retained):

• Leap year checking (Feb 29 validation) includes the logics: (divisible by 4 but not divisible by 100) or (divisible by 400)
• Supports years 1600 ~ 9999
• Supports dd/mm/YYYY, dd-mm-YYYY, dd.mm.YYYY (but not dd mm YYYY)
• Supports dd mmm YYYY, dd-mmm-YYYY, dd/mmm/YYYY, dd.mmm.YYYY (dd mmm YYYY newly added. mmm can be in CAPITAL e.g. DEC or Title format e.g. Dec)

Some additional minor touch-up as follows:

1. Included the fix by Ofir Luzon on February 14th 2019 to remove a comma that was in the regex which allowed dates like 29-0,-11 [error replicated to Alok Chaudhary's regex]

2. Replaced (\/|-|\.) by ([-.\/]) to minimize the use of backslash. \/ is still used in order to support some regex flavor e.g. PCRE(PHP) although some other regex flavor e.g. Python can simply use / inside the character class [ ]

3. Added a pair of parenthesis () surrounding the whole regex to make it a capturing group for the whole matching string. This is useful for people using findAll type of functions to get a matching item list (e.g. re.findall in Python). This enable us to capture all the matching strings within a mult-line string with the following codes:

re.findall sample codes:

match_list = re.findall(regex, source_string)
for item in match_list:
    print(item[0])

Extended regex image:

Credits should go to Ofir Luzon and Alok Chaudhary who created such excellent regexes for us all!

math.isnan(x)

Return True if x is a NaN (not a number), and False otherwise.

>>> import math
>>> x = float('nan')
>>> math.isnan(x)
True

s.TrimEnd();

The above is all I needed to remove '\r\n' from the end of my string.

The upvoted answer seems wrong to me. Firstly, it didn't work when I tried, secondly, if it did work I would expect that s.TrimEnd('\r', '\n') would only remove either a '\r' or a '\n', so I'd have to run it over my string twice - once for when '\n' was at the end and the second time for when '\r' was at the end (now that the '\n' was removed).

Just go to OUTPUT window, then click on Packages icon (it is located between Plot and Help icons). Remove "tick / check mark" from the package you wanted be unload.

For again using the package just put a "tick or Check mark" in front of package or use :

sys.path returns the list of paths

ref

sys.path

A list of strings that specifies the search path for modules. Initialized from the environment variable PYTHONPATH, plus an installation-dependent default.

As initialized upon program startup, the first item of this list, path[0], is the directory containing the script that was used to invoke the Python interpreter. If the script directory is not available (e.g. if the interpreter is invoked interactively or if the script is read from standard input), path[0] is the empty string, which directs Python to search modules in the current directory first. Notice that the script directory is inserted before the entries inserted as a result of PYTHONPATH.

import sys
dirs=sys.path
for path in dirs:
   print(path)

or you can print only first path by

print(dir[0])

I use this and it is pretty handy:

git config --global alias.mkdir '!git checkout -b $1; git status; git push -u origin $1; exit;'

Usage: git mkdir NEW_BRANCH

You don't even need git status; maybe, I just want to make sure everything is going well...

You can have BOTH the LOCAL and REMOTE branch with a single command.

I wrote a class that extends EditText which supports natively some validation methods and is actually very flexible.

Current, as I write, natively supported through xml attributes validation methods are:

1. alpha
2. alpha numeric
3. numeric
4. generic regexp
5. string emptyness

You can check it out here

Hope you enjoy it :)

There's whereIn():

$items = DB::table('items')->whereIn('id', [1, 2, 3])->get();

EDIT After some hunting around, this seems to be the best option:

https://github.com/googlemaps/js-info-bubble/blob/gh-pages/examples/example.html

You can see a customised version of this InfoBubble that I used on Dive Seven, a website for online scuba dive logging. It looks like this:

There are some more examples here. They definitely don't look as nice as the example in your screenshot, however.

I used xs2bush's method of getting an interval (using timeIntervalSinceDate) and expanded on it a little bit. I wanted to make sure that I was getting the required accuracy that I needed and also that I was not running down the battery by keeping the gps radio on more than necessary.

I keep location running continuously with the following settings:

locationManager.desiredAccuracy = kCLLocationAccuracyThreeKilometers;
locationManager.distanceFilter = 5;

this is a relatively low drain on the battery. When I'm ready to get my next periodic location reading, I first check to see if the location is within my desired accuracy, if it is, I then use the location. If it's not, then I increase the accuracy with this:

locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters;
locationManager.distanceFilter = 0;

get my location and then once I have the location I turn the accuracy back down again to minimize the drain on the battery. I have written a full working sample of this and also I have written the source for the server side code to collect the location data, store it to a database and allow users to view gps data in real time or retrieve and view previously stored routes. I have clients for iOS, android, windows phone and java me. All clients are natively written and they all work properly in the background. The project is MIT licensed.

The iOS project is targeted for iOS 6 using a base SDK of iOS 7. You can get the code here.

Please file an issue on github if you see any problems with it. Thanks.

Another (maybe faster for large directories) approach:

$ find dir1 | sed 's,^[^/]*/,,' | sort > dir1.txt && find dir2 | sed 's,^[^/]*/,,' | sort > dir2.txt
$ diff dir1.txt dir2.txt

The sed command removes the first directory component thanks to Erik`s post)

In response to the OP's question:

What are the correct version numbers for C#? What came out when? Why can't I find any answers about C# 3.5?

There is no such thing as C# 3.5 - the cause of confusion here is that the C# 3.0 is present in .NET 3.5. The language and framework are versioned independently, however - as is the CLR, which is at version 2.0 for .NET 2.0 through 3.5, .NET 4 introducing CLR 4.0, service packs notwithstanding. The CLR in .NET 4.5 has various improvements, but the versioning is unclear: in some places it may be referred to as CLR 4.5 (this MSDN page used to refer to it that way, for example), but the Environment.Version property still reports 4.0.xxx.

As of May 3, 2017, the C# Language Team created a history of C# versions and features on their GitHub repository: Features Added in C# Language Versions. There is also a page that tracks upcoming and recently implemented language features.

Clear Instructions On How to Add A Collaborator - 2020 Update

Pictures are worth a thousand words. Let's put that to the test:

Picture Instructions (Click to Zoom in):

.......and videos/gifs are worth another thousand more:

Gif Instructions (Click to Zoom in):

Hopefully the pictures/gif make it easier for you to configure this!

i think it should be

select convert(varchar(10),StandardCost) +'S' from DimProduct where ProductKey = 212

or

select cast(StandardCost as varchar(10)) + 'S' from DimProduct where ProductKey = 212

In vi, do a :%s/^M//g

To get the ^M hold the CTRL key, press V then M (Both while holding the control key) and the ^M will appear. This will find all occurrences and replace them with nothing.

I have used this mapping template to provide Body, Headers, Method, Path, and URL Query String Parameters to the Lambda event. I wrote a blog post explaining the template in more detail: http://kennbrodhagen.net/2015/12/06/how-to-create-a-request-object-for-your-lambda-event-from-api-gateway/

Here is the Mapping Template you can use:

{
  "method": "$context.httpMethod",
  "body" : $input.json('$'),
  "headers": {
    #foreach($param in $input.params().header.keySet())
    "$param": "$util.escapeJavaScript($input.params().header.get($param))" #if($foreach.hasNext),#end

    #end
  },
  "queryParams": {
    #foreach($param in $input.params().querystring.keySet())
    "$param": "$util.escapeJavaScript($input.params().querystring.get($param))" #if($foreach.hasNext),#end

    #end
  },
  "pathParams": {
    #foreach($param in $input.params().path.keySet())
    "$param": "$util.escapeJavaScript($input.params().path.get($param))" #if($foreach.hasNext),#end

    #end
  }  
}

One alternative is to change up your module. Generally if you are exporting an object with a bunch of functions on it, it's easier to export a bunch of named functions, e.g.

export function foo() { console.log('foo') }, 
export function bar() { console.log('bar') },
export function baz() { foo(); bar() }

In this case you are export all of the functions with names, so you could do

import * as fns from './foo';

to get an object with properties for each function instead of the import you'd use for your first example:

import fns from './foo';

For me, it was nothing more than re-importing the certificate with "Allow private key to be exported" checked.

I guess it is necessary, but it does make me nervous as it is a third party app accessing this certificate.

The accepted answer of this post will cause error in the case when the string length is lest than 5. So i have a better solution. We can use this simple code :

If(str.Length <= 5, str, str.Substring(str.Length - 5))

You can test it with variable length string.

    Dim str, result As String
    str = "11!"
    result = If(str.Length <= 5, str, str.Substring(str.Length - 5))
    MessageBox.Show(result)
    str = "I will be going to school in 2011!"
    result = If(str.Length <= 5, str, str.Substring(str.Length - 5))
    MessageBox.Show(result)

Another simple but efficient solution i found :

str.Substring(str.Length - Math.Min(5, str.Length))

EDIT: As pointed out in recent comments, this solution may BREAK your system.

You most likely don't want to remove python3.

Please refer to the other answers for possible solutions.

Outdated answer (not recommended)

sudo apt-get remove 'python3.*'

Here is a solution that worked for me.

function calduedate(ndays){

    var newdt = new Date(); var chrday; var chrmnth;
    newdt.setDate(newdt.getDate() + parseInt(ndays));

    var newdate = newdt.getFullYear();
    if(newdt.getMonth() < 10){
        newdate = newdate+'-'+'0'+newdt.getMonth();
    }else{
        newdate = newdate+'-'+newdt.getMonth();
    }
    if(newdt.getDate() < 10){
        newdate = newdate+'-'+'0'+newdt.getDate();
    }else{
        newdate = newdate+'-'+newdt.getDate();
    }

    alert("newdate="+newdate);

}

In Python, the 'null' object is the singleton None.

The best way to check things for "Noneness" is to use the identity operator, is:

if foo is None:
    ...

var resultList = checklist.Where(p => myList.All(l => p.value != l.value)).ToList();

You cannot assign to a list like lst[i] = something, unless the list already is initialized with at least i+1 elements. You need to use append to add elements to the end of the list. lst.append(something).

(You could use the assignment notation if you were using a dictionary).

Creating an empty list:

>>> l = [None] * 10
>>> l
[None, None, None, None, None, None, None, None, None, None]

Assigning a value to an existing element of the above list:

>>> l[1] = 5
>>> l
[None, 5, None, None, None, None, None, None, None, None]

Keep in mind that something like l[15] = 5 would still fail, as our list has only 10 elements.

range(x) creates a list from [0, 1, 2, ... x-1]

# 2.X only. Use list(range(10)) in 3.X.
>>> l = range(10)
>>> l
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

Using a function to create a list:

>>> def display():
...     s1 = []
...     for i in range(9): # This is just to tell you how to create a list.
...         s1.append(i)
...     return s1
... 
>>> print display()
[0, 1, 2, 3, 4, 5, 6, 7, 8]

List comprehension (Using the squares because for range you don't need to do all this, you can just return range(0,9) ):

>>> def display():
...     return [x**2 for x in range(9)]
... 
>>> print display()
[0, 1, 4, 9, 16, 25, 36, 49, 64]

Please refer the following link for better understanding about the difference between Const pointer and Pointer on a constant value.

constant pointer vs pointer on a constant value

Check out the solutions at "The Controls collection cannot be modified because the control contains code blocks"

The accepted solution on the other question worked for me -- change instances of <%= to <%#, which converts the code block from Response.Write to an evaluation block, which isn't restricted by the same limitations.

In this case though, like the accepted solution here suggests, you should add the controls to something other than a masterpage ContentPlaceHolder element, namely the asp:Placeholder control suggested.

I also encountered the same problem , the above methods will not work . I accidentally deleted the files in the following directory on it .

Folder emplacement:

~/Library/Developer/Xcode/DerivedData/

Generally you shouldn't rely on system properties to configure a webapp - they may be used to configure the container (e.g. Tomcat) but not an application running inside tomcat.

cliff.meyers has already mentioned the way you should rather use for your webapplication. That's the standard way, that also fits your question of being configurable through context.xml or server.xml means.

That said, should you really need system properties or other jvm options (like max memory settings) in tomcat, you should create a file named "bin/setenv.sh" or "bin/setenv.bat". These files do not exist in the standard archive that you download, but if they are present, the content is executed during startup (if you start tomcat via startup.sh/startup.bat). This is a nice way to separate your own settings from the standard tomcat settings and makes updates so much easier. No need to tweak startup.sh or catalina.sh.

(If you execute tomcat as windows servive, you usually use tomcat5w.exe, tomcat6w.exe etc. to configure the registry settings for the service.)

EDIT: Also, another possibility is to go for JNDI Resources.

Use the following:

xmllint --format

Resolved this problem using a Sequence ID defined in Oracle database.

ORACLE_DB_SEQ_ID is defined as a sequence for the table. Also look at the console to see the Hibernate SQL that is used to verify.

@Id
@Column(name = "MY_ID", unique = true, nullable = false)
@GeneratedValue(strategy=GenerationType.SEQUENCE, generator = "id_Sequence")
@SequenceGenerator(name = "id_Sequence", sequenceName = "ORACLE_DB_SEQ_ID")
Long myId;

Best practice for RESTful API design is that path params are used to identify a specific resource or resources, while query parameters are used to sort/filter those resources.

Here's an example. Suppose you are implementing RESTful API endpoints for an entity called Car. You would structure your endpoints like this:

GET /cars
GET /cars/:id
POST /cars
PUT /cars/:id
DELETE /cars/:id

This way you are only using path parameters when you are specifying which resource to fetch, but this does not sort/filter the resources in any way.

Now suppose you wanted to add the capability to filter the cars by color in your GET requests. Because color is not a resource (it is a property of a resource), you could add a query parameter that does this. You would add that query parameter to your GET /cars request like this:

GET /cars?color=blue

This endpoint would be implemented so that only blue cars would be returned.

As far as syntax is concerned, your URL names should be all lowercase. If you have an entity name that is generally two words in English, you would use a hyphen to separate the words, not camel case.

Ex. /two-words

You can use the Blob to get the string size in bytes.

Examples:

console.info(_x000D_
  new Blob(['']).size,                             // 4_x000D_
  new Blob(['']).size,                             // 4_x000D_
  new Blob(['']).size,                           // 8_x000D_
  new Blob(['']).size,                           // 8_x000D_
  new Blob(['I\'m a string']).size,                  // 12_x000D_
_x000D_
  // from Premasagar correction of Lauri's answer for_x000D_
  // strings containing lone characters in the surrogate pair range:_x000D_
  // https://stackoverflow.com/a/39488643/6225838_x000D_
  new Blob([String.fromCharCode(55555)]).size,       // 3_x000D_
  new Blob([String.fromCharCode(55555, 57000)]).size // 4 (not 6)_x000D_
);

The answers from Tomik and Peterdk work when you want your custom view to occupy the entire action bar, even hiding the native title.

But if you want your custom view to live side-by-side with the title (and fill all remaining space after the title is displayed), then may I refer you to the excellent answer from user Android-Developer here:

https://stackoverflow.com/a/16517395/614880

His code at bottom worked perfectly for me.

For the first question I think answer would be:

<your DataFrame>.rename(columns={'count':'Total_Numbers'})

or

<your DataFrame>.columns = ['ID', 'Region', 'Total_Numbers']

As for second one I'd say the answer would be no. It's possible to use it like 'df.ID' because of python datamodel:

Attribute references are translated to lookups in this dictionary, e.g., m.x is equivalent to m.dict["x"]

What I do when I wonder something like the question asked here is go to the source.

toBe()

expect().toBe() is defined as:

function toBe() {
  return {
    compare: function(actual, expected) {
      return {
        pass: actual === expected
      };
    }
  };
}

It performs its test with === which means that when used as expect(foo).toBe(true), it will pass only if foo actually has the value true. Truthy values won't make the test pass.

toBeTruthy()

expect().toBeTruthy() is defined as:

function toBeTruthy() {
  return {
    compare: function(actual) {
      return {
        pass: !!actual
      };
    }
  };
}

Type coercion

A value is truthy if the coercion of this value to a boolean yields the value true. The operation !! tests for truthiness by coercing the value passed to expect to a boolean. Note that contrarily to what the currently accepted answer implies, == true is not a correct test for truthiness. You'll get funny things like

> "hello" == true
false
> "" == true
false
> [] == true
false
> [1, 2, 3] == true
false

Whereas using !! yields:

> !!"hello"
true
> !!""
false
> !![1, 2, 3]
true
> !![] 
true

(Yes, empty or not, an array is truthy.)

toBeTrue()

expect().toBeTrue() is part of Jasmine-Matchers (which is registered on npm as jasmine-expect after a later project registered jasmine-matchers first).

expect().toBeTrue() is defined as:

function toBeTrue(actual) {
  return actual === true ||
    is(actual, 'Boolean') &&
    actual.valueOf();
}

The difference with expect().toBeTrue() and expect().toBe(true) is that expect().toBeTrue() tests whether it is dealing with a Boolean object. expect(new Boolean(true)).toBe(true) would fail whereas expect(new Boolean(true)).toBeTrue() would pass. This is because of this funny thing:

> new Boolean(true) === true
false
> new Boolean(true) === false
false

At least it is truthy:

> !!new Boolean(true)
true

Which is best suited for use with elem.isDisplayed()?

Ultimately Protractor hands off this request to Selenium. The documentation states that the value produced by .isDisplayed() is a promise that resolves to a boolean. I would take it at face value and use .toBeTrue() or .toBe(true). If I found a case where the implementation returns truthy/falsy values, I would file a bug report.

I just found out that there actually is a thread-based Pool interface in the multiprocessing module, however it is hidden somewhat and not properly documented.

It can be imported via

from multiprocessing.pool import ThreadPool

It is implemented using a dummy Process class wrapping a python thread. This thread-based Process class can be found in multiprocessing.dummy which is mentioned briefly in the docs. This dummy module supposedly provides the whole multiprocessing interface based on threads.

One convention I'd like to try out is naming static modules with a 'the' prefix. Check this out. When I use someone else's module, it's not easy to see how I'm supposed to use it. eg:

define(['Lightbox'],function(Lightbox) {
  var myLightbox = new Lightbox() // not sure whether this is a constructor (non-static) or not
  myLightbox.show('hello')
})

I'm thinking about trying a convention where static modules use 'the' to indicate their preexistence. Has anyone seen a better way than this? Would look like this:

define(['theLightbox'],function(theLightbox) {
  theLightbox.show('hello') // since I recognize the 'the' convention, I know it's static
})

I am an operating system that only allocates you memory in 10mb partitions.

Internal Fragmentation

• You ask for 17mb of memory
• I give you 20mb of memory

Fulfilling this request has just led to 3mb of internal fragmentation.

External Fragmentation

• You ask for 20mb of memory
• I give you 20mb of memory
• The 20mb of memory that I give you is not immediately contiguous next to another existing piece of allocated memory. In so handing you this memory, I have "split" a single unallocated space into two spaces.

Fulfilling this request has just led to external fragmentation

For iOS 7.* and iOS 6.1

The easiest method is to set the tableFooterView property:

- (void)viewDidLoad 
{
    [super viewDidLoad];

    // This will remove extra separators from tableview
    self.tableView.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];
}

For previous versions

You could add this to your TableViewController (this will work for any number of sections):

- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section {
     // This will create a "invisible" footer
     return 0.01f;
 }

and if it is not enough, add the following code too:

- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section
{        
    return [UIView new];

    // If you are not using ARC:
    // return [[UIView new] autorelease];
}

To check all the applications listening on all ports, there is command:

netstat -ntpl

In theory everything is possible but reality you find the numbers much lower than you might expect. I have been trying to address huge spaces on servers often and found that even though a server can have huge amounts of memory it surprised me that most software actually never can address it in real scenario's simply because the cpu's are not fast enough to really address them. Why would you say right ?! . Timings thats the endless downfall of every enormous machine which i have worked on. So i would advise to not go overboard by addressing huge amounts just because you can, but use what you think could be used. Actual values are often much lower than what you expected. Ofcourse non of us really uses hp 9000 systems at home and most of you actually ever will go near the capacity of your home system ever. For instance most users do not have more than 16 Gb of memory in their system. Ofcourse some of the casual gamers use work stations for a game once a month but i bet that is a very small percentage. So coming down to earth means i would address on a 8 Gb 64 bit system not much more than 512 mb for heapspace or if you go overboard try 1 Gb. I am pretty sure its even with these numbers pure overkill. I have constant monitored the memory usage during gaming to see if the addressing would make any difference but did not notice any difference at all when i addressed much lower values or larger ones. Even on the server/workstations there was no visible change in performance no matter how large i set the values. That does not say some jave users might be able to make use of more space addressed, but this far i have not seen any of the applications needing so much ever. Ofcourse i assume that their would be a small difference in performance if java instances would run out of enough heapspace to work with. This far i have not found any of it at all, however lack of real installed memory showed instant drops of performance if you set too much heapspace. When you have a 4 Gb system you run quickly out of heapspace and then you will see some errors and slowdowns because people address too much space which actually is not free in the system so the os starts to address drive space to make up for the shortage hence it starts to swap.

It looks like get-pip.py has been updated to use the environment variables http_proxy and https_proxy.

Windows:

set http_proxy=http://proxy.myproxy.com
set https_proxy=https://proxy.myproxy.com
python get-pip.py

Linux/OS X:

export http_proxy=http://proxy.myproxy.com
export https_proxy=https://proxy.myproxy.com
sudo -E python get-pip.py

However if this still doesn't work for you, you can always install pip through a proxy using setuptools' easy_install by setting the same environment variables.

Windows:

set http_proxy=http://proxy.myproxy.com
set https_proxy=https://proxy.myproxy.com
easy_install pip

Linux/OS X:

export http_proxy=http://proxy.myproxy.com
export https_proxy=https://proxy.myproxy.com
sudo -E easy_install pip

Then once it's installed, use:

pip install --proxy="user:password@server:port" packagename

From the pip man page:

--proxy
Have pip use a proxy server to access sites. This can be specified using "user:[email protected]:port" notation. If the password is left out, pip will ask for it.

You can use php code in files with extension .php and only there (iff other is not defined in your server settings).

Just rename your file *.html to *.php

If you want to allow php code processing in files of different format, you have two options to do that:

1) Modifying httpd.conf to allow this for all projects on your server, by adding:

AddHandler application/x-httpd-php .htm .html

2) Creating .htaccess file in your separate project top directory with:

<Files />
    AddType application/x-httpd-php .html
</Files>

For second option you need to allow use of .htaccess files in your httpd.conf, by adding the following settings:

AllowOverride All
AccessFileName .htaccess

*that is correct for Apache HTTP Server

There is another way. If you're passing an object by reference, that object's properties will appear in the function's local scope. I know this works for Safari (haven't checked other browsers) and I don't know if this feature has a name, but the below example illustrates its use.

Although in practice I don't think that this offers any functional value beyond the technique you're already using, it's a little cleaner semantically. And it still requires passing a object reference or an object literal.

function sum({ a:a, b:b}) {
    console.log(a+'+'+b);
    if(a==undefined) a=0;
    if(b==undefined) b=0;
    return (a+b);
}

// will work (returns 9 and 3 respectively)
console.log(sum({a:4,b:5}));
console.log(sum({a:3}));

// will not work (returns 0)
console.log(sum(4,5));
console.log(sum(4));

The datepicker('setDate') sets the date in the datepicket not in the input.

You should add the date and set it in the input.

var date2 = $('.pickupDate').datepicker('getDate');
var nextDayDate = new Date();
nextDayDate.setDate(date2.getDate() + 1);
$('input').val(nextDayDate);

If you're using AD you can use serverless binding to locate a domain controller for the default domain, then use LDAP://rootDSE to get information about the directory server, as described in the linked article.

If you are going to do it in pure CSS (using scss) but you have different elements/classes inside the same parent class you can use this version!!

  &:first-of-type:nth-last-of-type(1) {
    max-width: 100%;
  }

  @for $i from 2 through 10 {
    &:first-of-type:nth-last-of-type(#{$i}),
    &:first-of-type:nth-last-of-type(#{$i}) ~ & {
      max-width: (100% / #{$i});
    }
  }

What worked for me:

Client Side:

import axios from 'axios';

const url = 'http://127.0.0.1:5000/api/v1';

export default {
  login(credentials) {
    return axios
      .post(`${url}/users/login/`, credentials, {
        withCredentials: true,
        credentials: 'include',
      })
      .then((response) => response.data);
  },
};

Server Side:

const express = require('express');
const cors = require('cors');

const app = express();
const port = process.env.PORT || 5000;

app.use(
  cors({
    origin: [`http://localhost:${port}`, `https://localhost:${port}`],
    credentials: 'true',
  })
);

I had the same issue today using primefaces (primeng) and angular 7. Add the following to your style.css

p-button {
   -webkit-appearance: none !important;
}

i am also using a bit of bootstrap which has a reboot.css, that overrides it with (thats why i had to add !important)

button {
  -webkit-appearance: button;

}

An alternative would to use the jdbc.drivers System property to specify your required drivers(s) on the command line when you start the JVM.

Just move the extra condition into the JOIN ON criteria, this way the existence of b is not required to return a result

SELECT a.* FROM a 
    LEFT JOIN b ON a.group_id=b.group_id AND b.user_id!=$_SESSION{['user_id']} 
    WHERE a.keyword LIKE '%".$keyword."%' 
    GROUP BY group_id

man regex.h reports there is no manual entry for regex.h, but man 3 regex gives you a page explaining the POSIX functions for pattern matching.
The same functions are described in The GNU C Library: Regular Expression Matching, which explains that the GNU C Library supports both the POSIX.2 interface and the interface the GNU C Library has had for many years.

For example, for an hypothetical program that prints which of the strings passed as argument match the pattern passed as first argument, you could use code similar to the following one.

#include <errno.h>
#include <regex.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

void print_regerror (int errcode, size_t length, regex_t *compiled);

int
main (int argc, char *argv[])
{
  regex_t regex;
  int result;

  if (argc < 3)
    {
      // The number of passed arguments is lower than the number of
      // expected arguments.
      fputs ("Missing command line arguments\n", stderr);
      return EXIT_FAILURE;
    }

  result = regcomp (&regex, argv[1], REG_EXTENDED);
  if (result)
    {
      // Any value different from 0 means it was not possible to 
      // compile the regular expression, either for memory problems
      // or problems with the regular expression syntax.
      if (result == REG_ESPACE)
        fprintf (stderr, "%s\n", strerror(ENOMEM));
      else
        fputs ("Syntax error in the regular expression passed as first argument\n", stderr);
      return EXIT_FAILURE;               
    }
  for (int i = 2; i < argc; i++)
    {
      result = regexec (&regex, argv[i], 0, NULL, 0);
      if (!result)
        {
          printf ("'%s' matches the regular expression\n", argv[i]);
        }
      else if (result == REG_NOMATCH)
        {
          printf ("'%s' doesn't the regular expression\n", argv[i]);
        }
      else
        {
          // The function returned an error; print the string 
          // describing it.
          // Get the size of the buffer required for the error message.
          size_t length = regerror (result, &regex, NULL, 0);
          print_regerror (result, length, &regex);       
          return EXIT_FAILURE;
        }
    }

  /* Free the memory allocated from regcomp(). */
  regfree (&regex);
  return EXIT_SUCCESS;
}

void
print_regerror (int errcode, size_t length, regex_t *compiled)
{
  char buffer[length];
  (void) regerror (errcode, compiled, buffer, length);
  fprintf(stderr, "Regex match failed: %s\n", buffer);
}

The last argument of regcomp() needs to be at least REG_EXTENDED, or the functions will use basic regular expressions, which means that (for example) you would need to use a\{3\} instead of a{3} used from extended regular expressions, which is probably what you expect to use.

POSIX.2 has also another function for wildcard matching: fnmatch(). It doesn't allow to compile the regular expression, or get the substrings matching a sub-expression, but it is very specific for checking when a filename match a wildcard (e.g. it uses the FNM_PATHNAME flag).

The major difference between require and import, is that require will automatically scan node_modules to find modules, but import, which comes from ES6, won't.

Most people use babel to compile import and export, which makes import act the same as require.

The future version of Node.js might support import itself (actually, the experimental version already does), and judging by Node.js' notes, import won't support node_modules, it base on ES6, and must specify the path of the module.

So I would suggest you not use import with babel, but this feature is not yet confirmed, it might support node_modules in the future, who would know?

For reference, below is an example of how babel can convert ES6's import syntax to CommonJS's require syntax.

Say the fileapp_es6.js contains this import:

import format from 'date-fns/format';

This is a directive to import the format function from the node package date-fns.

The related package.json file could contain something like this:

"scripts": {
    "start": "node app.js",
    "build-server-file": "babel app_es6.js --out-file app.js",
    "webpack": "webpack"
}

The related .babelrc file could be something like this:

{
    "presets": [
        [
            "env",
            {
                "targets":
                {
                    "node": "current"
                }
            }
        ]
    ]
}

This build-server-file script defined in the package.json file is a directive for babel to parse the app_es6.js file and output the file app.js.

After running the build-server-file script, if you open app.js and look for the date-fns import, you will see it has been converted into this:

var _format = require("date-fns/format");

var _format2 = _interopRequireDefault(_format);

Most of that file is gobbledygook to most humans, however computers understand it.

Also for reference, as an example of how a module can be created and imported into your project, if you install date-fns and then open node_modules/date-fns/get_year/index.js you can see it contains:

var parse = require('../parse/index.js')

function getYear (dirtyDate) {
  var date = parse(dirtyDate)
  var year = date.getFullYear()
  return year
}

module.exports = getYear

Using the babel process above, your app_es6.js file could then contain:

import getYear from 'date-fns/get_year';

// Which year is 2 July 2014?
var result = getYear(new Date(2014, 6, 2))
//=> 2014

And babel would convert the imports to:

var _get_year = require("date-fns/get_year");

var _get_year2 = _interopRequireDefault(_get_year);

And handle all references to the function accordingly.

Please define brightness. If you're looking for how close to white the color is you can use Euclidean Distance from (255, 255, 255)

Looks like oldDTE.MyDateTime was null, so constructor tried to take it's Value - which threw.

You could fill the dependend cell (D2) by a User Defined Function (VBA Macro Function) that takes the value of the C2-Cell as input parameter, returning the current date as ouput.

Having C2 as input parameter for the UDF in D2 tells Excel that it needs to reevaluate D2 everytime C2 changes (that is if auto-calculation of formulas is turned on for the workbook).

EDIT:

Here is some code:

For the UDF:

    Public Function UDF_Date(ByVal data) As Date

        UDF_Date = Now()

    End Function

As Formula in D2:

=UDF_Date(C2)

You will have to give the D2-Cell a Date-Time Format, or it will show a numeric representation of the date-value.

And you can expand the formula over the desired range by draging it if you keep the C2 reference in the D2-formula relative.

Note: This still might not be the ideal solution because every time Excel recalculates the workbook the date in D2 will be reset to the current value. To make D2 only reflect the last time C2 was changed there would have to be some kind of tracking of the past value(s) of C2. This could for example be implemented in the UDF by providing also the address alonside the value of the input parameter, storing the input parameters in a hidden sheet, and comparing them with the previous values everytime the UDF gets called.

Addendum:

Here is a sample implementation of an UDF that tracks the changes of the cell values and returns the date-time when the last changes was detected. When using it, please be aware that:

• The usage of the UDF is the same as described above.

• The UDF works only for single cell input ranges.

• The cell values are tracked by storing the last value of cell and the date-time when the change was detected in the document properties of the workbook. If the formula is used over large datasets the size of the file might increase considerably as for every cell that is tracked by the formula the storage requirements increase (last value of cell + date of last change.) Also, maybe Excel is not capable of handling very large amounts of document properties and the code might brake at a certain point.

• If the name of a worksheet is changed all the tracking information of the therein contained cells is lost.

• The code might brake for cell-values for which conversion to string is non-deterministic.

• The code below is not tested and should be regarded only as proof of concept. Use it at your own risk.

  Public Function UDF_Date(ByVal inData As Range) As Date
  
      Dim wb As Workbook
      Dim dProps As DocumentProperties
      Dim pValue As DocumentProperty
      Dim pDate As DocumentProperty
      Dim sName As String
      Dim sNameDate As String
  
      Dim bDate As Boolean
      Dim bValue As Boolean
      Dim bChanged As Boolean
  
      bDate = True
      bValue = True
  
      bChanged = False
  
  
      Dim sVal As String
      Dim dDate As Date
  
      sName = inData.Address & "_" & inData.Worksheet.Name
      sNameDate = sName & "_dat"
  
      sVal = CStr(inData.Value)
      dDate = Now()
  
      Set wb = inData.Worksheet.Parent
  
      Set dProps = wb.CustomDocumentProperties
  
  On Error Resume Next
  
      Set pValue = dProps.Item(sName)
  
      If Err.Number <> 0 Then
          bValue = False
          Err.Clear
      End If
  
  On Error GoTo 0
  
      If Not bValue Then
          bChanged = True
          Set pValue = dProps.Add(sName, False, msoPropertyTypeString, sVal)
      Else
          bChanged = pValue.Value <> sVal
          If bChanged Then
              pValue.Value = sVal
          End If
      End If
  
  On Error Resume Next
  
      Set pDate = dProps.Item(sNameDate)
  
      If Err.Number <> 0 Then
          bDate = False
          Err.Clear
      End If
  
  On Error GoTo 0
  
      If Not bDate Then
          Set pDate = dProps.Add(sNameDate, False, msoPropertyTypeDate, dDate)
      End If
  
      If bChanged Then
          pDate.Value = dDate
      Else
          dDate = pDate.Value
      End If
  
  
      UDF_Date = dDate
   End Function
  

Make the insertion of the date conditional upon the range.

This has an advantage of not changing the dates unless the content of the cell is changed, and it is in the range C2:C2, even if the sheet is closed and saved, it doesn't recalculate unless the adjacent cell changes.

Adapted from this tip and @Paul S answer

Private Sub Worksheet_Change(ByVal Target As Range)
 Dim R1 As Range
 Dim R2 As Range
 Dim InRange As Boolean
    Set R1 = Range(Target.Address)
    Set R2 = Range("C2:C20")
    Set InterSectRange = Application.Intersect(R1, R2)

  InRange = Not InterSectRange Is Nothing
     Set InterSectRange = Nothing
   If InRange = True Then
     R1.Offset(0, 1).Value = Now()
   End If
     Set R1 = Nothing
     Set R2 = Nothing
 End Sub

Okay, so if later on down the line the issue is that you have a query that's greater than the allowable size (which may happen if it keeps growing) you're going to have to break it into chunks and execute the string values. So, let's say you have a stored procedure like the following:

CREATE PROCEDURE ExecuteMyHugeQuery
    @SQL VARCHAR(MAX) -- 2GB size limit as stated by Martin Smith
AS
BEGIN
    -- Now, if the length is greater than some arbitrary value
    -- Let's say 2000 for this example
    -- Let's chunk it
    -- Let's also assume we won't allow anything larger than 8000 total
    DECLARE @len INT
    SELECT @len = LEN(@SQL)

    IF (@len > 8000)
    BEGIN
        RAISERROR ('The query cannot be larger than 8000 characters total.',
                   16,
                   1);
    END

    -- Let's declare our possible chunks
    DECLARE @Chunk1 VARCHAR(2000),
            @Chunk2 VARCHAR(2000),
            @Chunk3 VARCHAR(2000),
            @Chunk4 VARCHAR(2000)

    SELECT @Chunk1 = '',
           @Chunk2 = '',
           @Chunk3 = '',
           @Chunk4 = ''

    IF (@len > 2000)
    BEGIN
        -- Let's set the right chunks
        -- We already know we need two chunks so let's set the first
        SELECT @Chunk1 = SUBSTRING(@SQL, 1, 2000)

        -- Let's see if we need three chunks
        IF (@len > 4000)
        BEGIN
            SELECT @Chunk2 = SUBSTRING(@SQL, 2001, 2000)

            -- Let's see if we need four chunks
            IF (@len > 6000)
            BEGIN
                SELECT @Chunk3 = SUBSTRING(@SQL, 4001, 2000)
                SELECT @Chunk4 = SUBSTRING(@SQL, 6001, (@len - 6001))
            END
              ELSE
            BEGIN
                SELECT @Chunk3 = SUBSTRING(@SQL, 4001, (@len - 4001))
            END
        END
          ELSE
        BEGIN
            SELECT @Chunk2 = SUBSTRING(@SQL, 2001, (@len - 2001))
        END
    END

    -- Alright, now that we've broken it down, let's execute it
    EXEC (@Chunk1 + @Chunk2 + @Chunk3 + @Chunk4)
END

Whether the take happens on the client or in the db depends on where you apply the take operator. If you apply it before you enumerate the query (i.e. before you use it in a foreach or convert it to a collection) the take will result in the "top n" SQL operator being sent to the db. You can see this if you run SQL profiler. If you apply the take after enumerating the query it will happen on the client, as LINQ will have had to retrieve the data from the database for you to enumerate through it

select id,    
NewsHeadline as news_headline,    
NewsText as news_text,    
state,    
CreatedDate as created_on    
from News    
WHERE CreatedDate>=DATEADD(DAY,-7,GETDATE())

Yes, your example is correct. Anonymous classes can implement interfaces, and that's the only time I can think of that you'll see a class implementing an interface without the "implements" keyword. Check out another code sample right here:

interface ProgrammerInterview {
    public void read();
}

class Website {
    ProgrammerInterview p = new ProgrammerInterview() {
        public void read() {
            System.out.println("interface ProgrammerInterview class implementer");
        }
    };
}

This works fine. Was taken from this page:

http://www.programmerinterview.com/index.php/java-questions/anonymous-class-interface/

My first choice is Android Studio. its has great feature to develop android application.

Eclipse is not that hard to learn also.If you're going to be learning Android development from the start, I can recommend Hello, Android, which I just finished. It shows you exactly how to use all the features of Eclipse that are useful for developing Android apps. There's also a brief section on getting set up to develop from the command line and from other IDEs.

Use this regular expression if you don't want to start with zero:

^[1-9]([0-9]{1,45}$)

If you don't mind starting with zero, use:

^[0-9]{1,45}$

In the AppCompatActivity for example you can do

public class GrandStatActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_grand_stat);
    }

    @Override
    public void onResume() {
        super.onResume();

        // Display custom title
        ActionBar actionBar = this.getSupportActionBar();
        actionBar.setTitle(R.string.fragment_title_grandstats);

        // Display the back arrow
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setDisplayShowHomeEnabled(true);
    }

    // Back arrow click event to go to the parent Activity
    @Override
    public boolean onSupportNavigateUp() {
        onBackPressed();
        return true;
    }

}

You can get top and left without traversing DOM like this:

function getCoords(elem) { // crossbrowser version
    var box = elem.getBoundingClientRect();

    var body = document.body;
    var docEl = document.documentElement;

    var scrollTop = window.pageYOffset || docEl.scrollTop || body.scrollTop;
    var scrollLeft = window.pageXOffset || docEl.scrollLeft || body.scrollLeft;

    var clientTop = docEl.clientTop || body.clientTop || 0;
    var clientLeft = docEl.clientLeft || body.clientLeft || 0;

    var top  = box.top +  scrollTop - clientTop;
    var left = box.left + scrollLeft - clientLeft;

    return { top: Math.round(top), left: Math.round(left) };
}

if( a['desiredKey'] !== undefined )
{
   // it exists
}

Use (eventName) for while binding event to DOM, basically () is used for event binding. Also use ngModel to get two way binding for myModel variable.

Markup

<input type="text" [(ngModel)]="myModel" (blur)="onBlurMethod()">

Code

export class AppComponent { 
  myModel: any;
  constructor(){
    this.myModel = '123';
  }
  onBlurMethod(){
   alert(this.myModel) 
  }
}

Demo

Alternative(not preferable)

<input type="text" #input (blur)="onBlurMethod($event.target.value)">

Demo

For model driven form to fire validation on blur, you could pass updateOn parameter.

ctrl = new FormControl('', {
   updateOn: 'blur', //default will be change
   validators: [Validators.required]
}); 

Design Docs

It's an asynchronous request, meaning once it's sent it's out there.

In case your server is starting a very expensive operation due to the AJAX request, the best you can do is open your server to listen for cancel requests, and send a separate AJAX request notifying the server to stop whatever it's doing.

Otherwise, simply ignore the AJAX response.

BDD Style Solution (Updated to Java 8)

Mockito alone is not the best solution for handling exceptions, use Mockito with Catch-Exception

Mockito + Catch-Exception + AssertJ

given(otherServiceMock.bar()).willThrow(new MyException());

when(() -> myService.foo());

then(caughtException()).isInstanceOf(MyException.class);

Sample code

• Mockito + Catch-Exception + Assertj full sample

Dependencies

• eu.codearte.catch-exception:catch-exception:2.0
• org.assertj:assertj-core:3.12.2

The solution is to run an NTP client , just run the command as below

#ntpdate 172.16.12.100

172.16.12.100 is the ntp server

Use short circuit evaluation:

s = a or '' + b or ''

Since + is not a very good operation on strings, better use format strings:

s = "%s%s" % (a or '', b or '')

The methods are "basically" the same, except handling null.

Pen pen = null; 
Convert.ToString(pen); // No exception thrown
pen.ToString(); // Throws NullReferenceException

From MSDN :
Convert.ToString Method

Converts the specified value to its equivalent string representation.

Object.ToString

Returns a string that represents the current object.

Python 3: new exec (execfile dropped) !

The execfile solution is valid only for Python 2. Python 3 dropped the execfile function - and promoted the exec statement to a builtin universal function. As the comment in Python 3.0's changelog and Hi-Angels comment suggest:

use

exec(open(<filename.py>).read())

instead of

execfile(<filename.py>)

To summarize the other answers, for general use:

Multi-line if...then statement

if [ foo ]; then
    a; b
elif [ bar ]; then
    c; d
else
    e; f
fi

Single-line version

if [ foo ]; then a && b; elif [ bar ]; c && d; else e && f; fi

Using the OR operator

( foo && a && b ) || ( bar && c && d ) || e && f;

Notes

Remember that the AND and OR operators evaluate whether or not the result code of the previous operation was equal to true/success (0). So if a custom function returns something else (or nothing at all), you may run into problems with the AND/OR shorthand. In such cases, you may want to replace something like ( a && b ) with ( [ a == 'EXPECTEDRESULT' ] && b ), etc.

Also note that ( and [ are technically commands, so whitespace is required around them.

Instead of a group of && statements like then a && b; else, you could also run statements in a subshell like then $( a; b ); else, though this is less efficient. The same is true for doing something like result1=$( foo; a; b ); result2=$( bar; c; d ); [ "$result1" -o "$result2" ] instead of ( foo && a && b ) || ( bar && c && d ). Though at that point you'd be getting more into less-compact, multi-line stuff anyway.

You can use

org.apache.commons.lang3.StringUtils.containsIgnoreCase(CharSequence str,
                                     CharSequence searchStr);

Checks if CharSequence contains a search CharSequence irrespective of case, handling null. Case-insensitivity is defined as by String.equalsIgnoreCase(String).

A null CharSequence will return false.

This one will be better than regex as regex is always expensive in terms of performance.

For official doc, refer to : StringUtils.containsIgnoreCase

Update :

If you are among the ones who

• don't want to use Apache commons library
• don't want to go with the expensive regex/Pattern based solutions,
• don't want to create additional string object by using toLowerCase,

you can implement your own custom containsIgnoreCase using java.lang.String.regionMatches

public boolean regionMatches(boolean ignoreCase,
                             int toffset,
                             String other,
                             int ooffset,
                             int len)

ignoreCase : if true, ignores case when comparing characters.

public static boolean containsIgnoreCase(String str, String searchStr)     {
    if(str == null || searchStr == null) return false;

    final int length = searchStr.length();
    if (length == 0)
        return true;

    for (int i = str.length() - length; i >= 0; i--) {
        if (str.regionMatches(true, i, searchStr, 0, length))
            return true;
    }
    return false;
}

Go to Tools->Options on menu on main window. Under Environment container, you can see Fonts and Colors. You can select font and color which you want.

final means that the value cannot be changed after initialization, that's what makes it a constant. static means that instead of having space allocated for the field in each object, only one instance is created for the class.

So, static final means only one instance of the variable no matter how many objects are created and the value of that variable can never change.

Windows solution: Assuming all files contained in sub-directory 'src', and you want to compile them to 'bin'.

for /r src %i in (*.java) do javac %i -sourcepath src -d bin

If src contains a .java file immediately below it then this is faster

javac src\\*.java -d bin

I am not sure what you mean by "dynamic". If you mean adding items to a dictionary at runtime, it is as easy as dictionary[key] = value.

If you wish to create a dictionary with key,value to start with (at compile time) then use (surprise!)

dictionary[key] = value

In the HTML page you have to to put your css code between the tags, while in the body a div which has as id rectangle. Here the code:

<!doctype>
<html>
<head>
<style>
#rectangle 
{
   all your css code
}
</style>
</head>
<body>
<div id="rectangle"></div>

I tried maximum to use the comparator with primitive type itself. At-last i concluded that there is no way to cheat the comparator.This is my implementation.

public class ArrSortComptr {
    public static void main(String[] args) {

         int[] array = { 3, 2, 1, 5, 8, 6 };
         int[] sortedArr=SortPrimitiveInt(new intComp(),array);
         System.out.println("InPut "+ Arrays.toString(array));
         System.out.println("OutPut "+ Arrays.toString(sortedArr));

    }
 static int[] SortPrimitiveInt(Comparator<Integer> com,int ... arr)
 {
    Integer[] objInt=intToObject(arr);
    Arrays.sort(objInt,com);
    return intObjToPrimitive(objInt);

 }
 static Integer[] intToObject(int ... arr)
 {
    Integer[] a=new Integer[arr.length];
    int cnt=0;
    for(int val:arr)
      a[cnt++]=new Integer(val);
    return a;
 }
 static int[] intObjToPrimitive(Integer ... arr)
 {
     int[] a=new int[arr.length];
     int cnt=0;
     for(Integer val:arr)
         if(val!=null)
             a[cnt++]=val.intValue();
     return a;

 }

}
class intComp implements Comparator<Integer>
{

    @Override //your comparator implementation.
    public int compare(Integer o1, Integer o2) {
        // TODO Auto-generated method stub
        return o1.compareTo(o2);
    }

}

@Roman: I can't say that this is a good example but since you asked this is what came to my mind. Suppose in an array you want to sort number's just based on their absolute value.

Integer d1=Math.abs(o1);
Integer d2=Math.abs(o2);
return d1.compareTo(d2);

Another example can be like you want to sort only numbers greater than 100.It actually depends on the situation.I can't think of any more situations.Maybe Alexandru can give more examples since he say's he want's to use a comparator for int array.

Since you know how many types of layout you would have - it's possible to use those methods.

getViewTypeCount() - this methods returns information how many types of rows do you have in your list

getItemViewType(int position) - returns information which layout type you should use based on position

Then you inflate layout only if it's null and determine type using getItemViewType.

Look at this tutorial for further information.

To achieve some optimizations in structure that you've described in comment I would suggest:

• Storing views in object called ViewHolder. It would increase speed because you won't have to call findViewById() every time in getView method. See List14 in API demos.
• Create one generic layout that will conform all combinations of properties and hide some elements if current position doesn't have it.

I hope that will help you. If you could provide some XML stub with your data structure and information how exactly you want to map it into row, I would be able to give you more precise advise. By pixel.

IMO, this is the cleanest answer:

<form action="" method="get">_x000D_
  Name: <input type="text" name="name"/><br/>_x000D_
  Pwd: <input type="password" name="password"/><br/>_x000D_
  <div class="yourCustomDiv"/>_x000D_
  <input type="submit" style="display:none"/>_x000D_
</form>

Better yet, if you are using javascript to submit the form using the custom div, you should also use javascript to create it, and to set the display:none style on the button. This way users with javascript disabled will still see the submit button and can click on it.

It has been noted that display:none will cause IE to ignore the input. I created a new JSFiddle example that starts as a standard form, and uses progressive enhancement to hide the submit and create the new div. I did use the CSS styling from StriplingWarrior.

I went through the exercise to capture low level packet exchange, and found that network connection is only triggered by operations like getInputStream, getOutputStream, getResponseCode, getResponseMessage etc.

Here is the packet exchange captured when I try to write a small program to upload file to Dropbox.

Below is my toy program and annotation

    /* Create a connection LOCAL object,
     * the openConnection() function DOES NOT initiate
     * any packet exchange with the remote server.
     * 
     * The configurations only setup the LOCAL
     * connection object properties.
     */
    HttpURLConnection connection = (HttpURLConnection) dst.openConnection();
    connection.setDoOutput(true);
    connection.setRequestMethod("POST");
    ...//headers setup
    byte[] testContent = {0x32, 0x32};

    /**
     * This triggers packet exchange with the remote
     * server to create a link. But writing/flushing
     * to a output stream does not send out any data.
     * 
     * Payload are buffered locally.
     */
    try (BufferedOutputStream outputStream = new BufferedOutputStream(connection.getOutputStream())) {
        outputStream.write(testContent);
        outputStream.flush();
    }

    /**
     * Trigger payload sending to the server.
     * Client get ALL responses (including response code,
     * message, and content payload) 
     */
    int responseCode = connection.getResponseCode();
    System.out.println(responseCode);

    /* Here no further exchange happens with remote server, since
     * the input stream content has already been buffered
     * in previous step
     */
    try (InputStream is = connection.getInputStream()) {
        Scanner scanner = new Scanner(is);
        StringBuilder stringBuilder = new StringBuilder();
        while (scanner.hasNextLine()) {
        stringBuilder.append(scanner.nextLine()).append(System.lineSeparator());
        }
    }

    /**
     * Trigger the disconnection from the server.
     */
    String responsemsg = connection.getResponseMessage();
    System.out.println(responsemsg);
    connection.disconnect();

You need to git add my_project to stage your new folder. Then git add my_project/* to stage its contents. Then commit what you've staged using git commit and finally push your changes back to the source using git push origin master (I'm assuming you wish to push to the master branch).

Maybe the question is unclear that why no answer was matching it but I had the same error message when I was trying to mount sshfs which required sudo : the command is something like this :

sshfs -o sftp_server="/usr/bin/sudo /usr/lib/openssh/sftp-server" [email protected]:/var/www /mnt/sshfs/www

by adding the option -o debug

sshfs -o debug -o sftp_server="/usr/bin/sudo /usr/lib/openssh/sftp-server" [email protected]:/var/www /mnt/sshfs/www

I had the same message of this question :

sudo: no tty present and no askpass program specified

So by reading others answer I became to make a file in /etc/sudoer.d/user on my.server.tld with :

user ALL=NOPASSWD: /usr/lib/openssh/sftp-server

and now I able to mount the drive without giving too much extra right to my user.

If you want the #header to be the same width as your container, with 10px of padding, you can leave out its width declaration. That will cause it to implicitly take up its entire parent's width (since a div is by default a block level element).

Then, since you haven't defined a width on it, the 10px of padding will be properly applied inside the element, rather than adding to its width:

#container {
    position: relative;
    width: 80%;
}

#header {
    position: relative;
    height: 50px;
    padding: 10px;
}

You can see it in action here.

The key when using percentage widths and pixel padding/margins is not to define them on the same element (if you want to accurately control the size). Apply the percentage width to the parent and then the pixel padding/margin to a display: block child with no width set.

Update

Another option for dealing with this is to use the box-sizing CSS rule:

#container { 
    -webkit-box-sizing: border-box; /* Safari/Chrome, other WebKit */
    -moz-box-sizing: border-box;    /* Firefox, other Gecko */
    box-sizing: border-box;         /* Opera/IE 8+ */

    /* Since this element now uses border-box sizing, the 10px of horizontal
       padding will be drawn inside the 80% width */
    width: 80%;
    padding: 0 10px;
}

Here's a post talking about how box-sizing works.

date_default_timezone_set('Australia/Melbourne');   
$time = date("Y-m-d H:i:s", time()); 

Here are the settings visually:

You can't import classes from the default package. You should avoid using the default package except for very small example programs.

From the Java language specification:

It is a compile time error to import a type from the unnamed package.

Solution with JSON aggregation:

CREATE TEMP TABLE t (
  section   text
, status    text
, ct        integer  -- don't use "count" as column name.
);

INSERT INTO t VALUES 
  ('A', 'Active', 1), ('A', 'Inactive', 2)
, ('B', 'Active', 4), ('B', 'Inactive', 5)
                   , ('C', 'Inactive', 7); 


SELECT section,
       (obj ->> 'Active')::int AS active,
       (obj ->> 'Inactive')::int AS inactive
FROM (SELECT section, json_object_agg(status,ct) AS obj
      FROM t
      GROUP BY section
     )X

From the HTTP core module docs:

1. Directives with the "=" prefix that match the query exactly. If found, searching stops.
2. All remaining directives with conventional strings. If this match used the "^~" prefix, searching stops.
3. Regular expressions, in the order they are defined in the configuration file.
4. If #3 yielded a match, that result is used. Otherwise, the match from #2 is used.

Example from the documentation:

location  = / {
  # matches the query / only.
  [ configuration A ] 
}
location  / {
  # matches any query, since all queries begin with /, but regular
  # expressions and any longer conventional blocks will be
  # matched first.
  [ configuration B ] 
}
location /documents/ {
  # matches any query beginning with /documents/ and continues searching,
  # so regular expressions will be checked. This will be matched only if
  # regular expressions don't find a match.
  [ configuration C ] 
}
location ^~ /images/ {
  # matches any query beginning with /images/ and halts searching,
  # so regular expressions will not be checked.
  [ configuration D ] 
}
location ~* \.(gif|jpg|jpeg)$ {
  # matches any request ending in gif, jpg, or jpeg. However, all
  # requests to the /images/ directory will be handled by
  # Configuration D.   
  [ configuration E ] 
}

If it's still confusing, here's a longer explanation.

You can use JavaScript Timing Events to call function after certain interval of time:

This shows the alert box after 3 seconds:

setInterval(function(){alert("Hello")},3000);

You can use two method of time event in javascript.i.e.

1. setInterval(): executes a function, over and over again, at specified time intervals
2. setTimeout() : executes a function, once, after waiting a specified number of milliseconds

Adding to Eric Jablow's answer, here is a possible solution (it worked for me - linux mint 14 /nadia)

find /path/to/search/ -type f -name "glob-to-find-files" | xargs cp -t /target/path/

You can refer to "How can I use xargs to copy files that have spaces and quotes in their names?" as well.

You can use RegEdit to export the following two keys:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment

HKEY_CURRENT_USER\Environment

The first set are system/global environment variables; the second set are user-level variables. Edit as needed and then import the .reg files on the new machine.

H vs h is difference between 24 hour vs 12 hour format.

Another way of doing the same could be using the Gson Class

String filename = "path/to/file/abc.json";
Gson gson = new Gson();
JsonReader reader = new JsonReader(new FileReader(filename));
SampleClass data = gson.fromJson(reader, SampleClass.class);

This will give an object obtained after parsing the json string to work with.

The reason behind this error is : Flask app is already running, hasn't shut down and in middle of that we try to start another instance by: with app.app_context(): #Code Before we use this with statement we need to make sure that scope of the previous running app is closed.

I do appreciate the answer of "Chang She", really, but the iterrows() function takes long time on large dataset. I faced that issue and I came to this.

# First, reset_index to make the index a column
a = a.reset_index().rename(columns={'index':'duplicated_idx'})

# Get a longer series with exploded cells to rows
series = pd.DataFrame(a['var1'].str.split('/')
                      .tolist(), index=a.duplicated_idx).stack()

# New df from series and merge with the old one
b = series.reset_index([0, 'duplicated_idx'])
b = b.rename(columns={0:'var1'})

# Optional & Advanced: In case, there are other columns apart from var1 & var2
b.merge(
    a[a.columns.difference(['var1'])],
    on='duplicated_idx')

# Optional: Delete the "duplicated_index"'s column, and reorder columns
b = b[a.columns.difference(['duplicated_idx'])]

Also not sure if I fully understand your case, but here is config snippet to create separate vendor chunks for each of your bundles:

entry: {
  bundle1: './build/bundles/bundle1.js',
  bundle2: './build/bundles/bundle2.js',
  'vendor-bundle1': [
    'react',
    'react-router'
  ],
  'vendor-bundle2': [
    'react',
    'react-router',
    'flummox',
    'immutable'
  ]
},

plugins: [
  new webpack.optimize.CommonsChunkPlugin({
    name: 'vendor-bundle1',
    chunks: ['bundle1'],
    filename: 'vendor-bundle1.js',
    minChunks: Infinity
  }),
  new webpack.optimize.CommonsChunkPlugin({
    name: 'vendor-bundle2',
    chunks: ['bundle2'],
    filename: 'vendor-bundle2-whatever.js',
    minChunks: Infinity
  }),
]

And link to CommonsChunkPlugin docs: http://webpack.github.io/docs/list-of-plugins.html#commonschunkplugin

A string literal is delimited by quotation marks and is of type char* not char.

Example: "hello"

So when you compare a char to a char* you will get that same compiling error.

char c = 'c';
char *p = "hello";

if(c==p)//compiling error
{
} 

To fix use a char literal which is delimited by single quotes.

Example: 'c'

You should use filter and exclude like this

results = Model.objects.exclude(a=true).filter(x=5)

If you need to wrap a private method inside a transaction and don't want to use aspectj, you can use TransactionTemplate.

@Service
public class MyService {

    @Autowired
    private TransactionTemplate transactionTemplate;

    private void process(){
        transactionTemplate.execute(new TransactionCallbackWithoutResult() {
            @Override
            protected void doInTransactionWithoutResult(TransactionStatus status) {
                processInTransaction();
            }
        });

    }

    private void processInTransaction(){
        //...
    }

}

The Background Panel entry shows a couple of different ways depending on your requirements.

Which parameter between (data / json / files) should be used,it's actually depends on a request header named ContentType(usually check this through developer tools of your browser),

when the Content-Type is application/x-www-form-urlencoded, code should be:

requests.post(url, data=jsonObj)

when the Content-Type is application/json, your code is supposed to be one of below:

requests.post(url, json=jsonObj)

requests.post(url, data=jsonstr, headers={"Content-Type":"application/json"})

when the Content-Type is multipart/form-data, it's used to upload files, so your code should be:

requests.post(url, files=xxxx)

Just a note - I've been using wildcard selectors in jQuery to grab items that are obfuscated by ASP.NET Client IDs - this might help you too:

<asp:DropDownList id="MyDropDown" runat="server" />

$("[id* = 'MyDropDown']").append("<option value='-1'>&nbsp;</option>"); //etc

Note the id* wildcard- this will find your element even if the name is "ctl00$ctl00$ContentPlaceHolder1$ContentPlaceHolder1$MyDropDown"

For completeness, this is what you would have found in the svn book, had you known what to look for. It's what you've discovered already:

Undoing Changes

Resurrecting Deleted Items

Same thing, from the more recent (and detailed) version of the book:

Undoing Changes

Resurrecting Deleted Items

Look here:

http://tratt.net/laurie/tech_articles/articles/tail_call_optimization

As you probably know, recursive function calls can wreak havoc on a stack; it is easy to quickly run out of stack space. Tail call optimization is way by which you can create a recursive style algorithm that uses constant stack space, therefore it does not grow and grow and you get stack errors.

In Bootstrap 3 I've added a table-no-border class

.table-no-border>thead>tr>th, 
.table-no-border>tbody>tr>th, 
.table-no-border>tfoot>tr>th, 
.table-no-border>thead>tr>td, 
.table-no-border>tbody>tr>td, 
.table-no-border>tfoot>tr>td {
  border-top: none; 
}

I'm not sure how you could just check if something isn't undefined and at the same time get an error that it is undefined. What browser are you using?

You could check in the following way (extra = and making length a truthy evaluation)

if (typeof(sub.from) !== 'undefined' && sub.from.length) {

[update]

I see that you reset sub and thereby reset sub.from but fail to re check if sub.from exist:

for (var i = 0; i < sub.from.length; i++) {//<== assuming sub.from.exist
            mainid = sub.from[i]['id'];
            var sub = afcHelper_Submissions[mainid]; // <== re setting sub

My guess is that the error is not on the if statement but on the for(i... statement. In Firebug you can break automatically on an error and I guess it'll break on that line (not on the if statement).

If you're using the PageFactory pattern or already have a reference to your WebElement, then you probably want to set the attribute, using your existing reference to the WebElement. (Rather than doing a document.getElementById(...) in your javascript)

The following sample allows you to set the attribute, using your existing WebElement reference.

Code Snippet

import org.openqa.selenium.WebElement;
import org.openqa.selenium.remote.RemoteWebDriver;
import org.openqa.selenium.support.FindBy;

public class QuickTest {

    RemoteWebDriver driver;

    @FindBy(id = "foo")
    private WebElement username;

    public void exampleUsage(RemoteWebDriver driver) {
        setAttribute(username, "attr", "10");
        setAttribute(username, "value", "bar");
    }

    public void setAttribute(WebElement element, String attName, String attValue) {
        driver.executeScript("arguments[0].setAttribute(arguments[1], arguments[2]);", 
                element, attName, attValue);
    }
}

You have a variable that contains an address of something. That's a pointer.

Then you have another variable that contains the address of the first variable. That's a pointer to pointer.

I have tried similar issue and works fine, try it. It can handle different orientations between PDFs.

    // array to hold list of PDF files to be merged
    $files = array("a.pdf", "b.pdf", "c.pdf");
    $pageCount = 0;
    // initiate FPDI
    $pdf = new FPDI();

    // iterate through the files
    foreach ($files AS $file) {
        // get the page count
        $pageCount = $pdf->setSourceFile($file);
        // iterate through all pages
        for ($pageNo = 1; $pageNo <= $pageCount; $pageNo++) {
            // import a page
            $templateId = $pdf->importPage($pageNo);
            // get the size of the imported page
            $size = $pdf->getTemplateSize($templateId);

            // create a page (landscape or portrait depending on the imported page size)
            if ($size['w'] > $size['h']) {
                $pdf->AddPage('L', array($size['w'], $size['h']));
            } else {
                $pdf->AddPage('P', array($size['w'], $size['h']));
            }

            // use the imported page
            $pdf->useTemplate($templateId);

            $pdf->SetFont('Helvetica');
            $pdf->SetXY(5, 5);
            $pdf->Write(8, 'Generated by FPDI');
        }
    }

Well, the Qt FAQ says:

  printf("str2: %s", c_str2);
  return app.exec();
}

$ npm config set https-proxy "http://192.168.1.101:4128"

where 192.168.1.101 is proxy ip and 4128 is port. change according to your proxy settings.

Works for me.

Latest and greatest way to do this:

Node supports file and buffer operations with the base64 encoding:

const fs = require('fs');
const contents = fs.readFileSync('/path/to/file.jpg', {encoding: 'base64'});

Or using the new promises API:

const fs = require('fs').promises;
const contents = await fs.readFile('/path/to/file.jpg', {encoding: 'base64'});

You can use the errorPlacement option to override the error message display with little css. Because css on its own will not be enough to produce the effect you need.

$(document).ready(function(){
    $("#myForm").validate({
        rules: {
            "elem.1": {
                required: true,
                digits: true
            },
            "elem.2": {
                required: true
            }
        },
        errorElement: "div",
        wrapper: "div",  // a wrapper around the error message
        errorPlacement: function(error, element) {
            offset = element.offset();
            error.insertBefore(element)
            error.addClass('message');  // add a class to the wrapper
            error.css('position', 'absolute');
            error.css('left', offset.left + element.outerWidth());
            error.css('top', offset.top);
        }

    });
});

You can play with the left and top css attributes to show the error message on top, left, right or bottom of the element. For example to show the error on the top:

    errorPlacement: function(error, element) {
        element.before(error);
        offset = element.offset();
        error.css('left', offset.left);
        error.css('top', offset.top - element.outerHeight());
    }

And so on. You can refer to jQuery documentation about css for more options.

Here is the css I used. The result looks exactly like the one you want. With as little CSS as possible:

div.message{
    background: transparent url(msg_arrow.gif) no-repeat scroll left center;
    padding-left: 7px;
}

div.error{
    background-color:#F3E6E6;
    border-color: #924949;
    border-style: solid solid solid none;
    border-width: 2px;
    padding: 5px;
}

And here is the background image you need:

_{(source: scriptiny.com)}

If you want the error message to be displayed after a group of options or fields. Then group all those elements inside one container a 'div' or a 'fieldset'. Add a special class to all of them 'group' for example. And add the following to the begining of the errorPlacement function:

errorPlacement: function(error, element) {
    if (element.hasClass('group')){
        element = element.parent();
    }
    ...// continue as previously explained

If you only want to handle specific cases you can use attr instead:

if (element.attr('type') == 'radio'){
    element = element.parent();
}

That should be enough for the error message to be displayed next to the parent element.

You may need to change the width of the parent element to be less than 100%.

I've tried your code and it is working perfectly fine for me. Here is a preview:

I just made a very small adjustment to the message padding to make it fit in the line:

div.error {
    padding: 2px 5px;
}

You can change those numbers to increase/decrease the padding on top/bottom or left/right. You can also add a height and width to the error message. If you are still having issues, try to replace the span with a div

<div class="group">
<input type="radio" class="checkbox" value="P" id="radio_P" name="radio_group_name"/>
<label for="radio_P">P</label>
<input type="radio" class="checkbox" value="S" id="radio_S" name="radio_group_name"/>
<label for="radio_S">S</label>
</div>

And then give the container a width (this is very important)

div.group {
    width: 50px; /* or any other value */
}

About the blank page. As I said I tried your code and it is working for me. It might be something else in your code that is causing the issue.

1. Click somewhere on the chart to select it.

2. You should now see 3 new tabs appear at the top of the screen called "Design", "Layout" and "Format".

3. Click on the "Design" tab.

4. There will be a button called "Switch Row/Column" within the "data" group, click it.

Just a helpful hint, there is a company called Yodlee.com who provides this data. They do charge for the API. Companies like Mint.com use this API to gather bank and financial account data.

Also, checkout https://plaid.com/, they are a similar company Yodlee.com and provide both authentication API for several banks and REST-based transaction fetching endpoints.

just another way to do it.

Label lbl = new Label();
new ToolTip().SetToolTip(lbl, "tooltip text here");

First things first, i'd not like that as a user.

The best way to do is probably using a small flash applet that plays your sound in the background.

Also answered here: Cross-platform, cross-browser way to play sound from Javascript?

do this in two steps:

1. replace not letter characters with this regex:

   [\/\&%#\$]

2. replace quotes with this regex:

   [\"\']

and use preg_replace:

$stringWithoutNonLetterCharacters = preg_replace("/[\/\&%#\$]/", "_", $yourString);
$stringWithQuotesReplacedWithSpaces = preg_replace("/[\"\']/", " ", $stringWithoutNonLetterCharacters);

I had a similar problem: git diff would show differences, but git diff <filename> would not. It turned out that I set LESS to a string including -F (--quit-if-one-screen). Removing that flag solved the problem.

Multiple statements on one line may include semicolons as separators. For example: http://docs.python.org/reference/compound_stmts.html In your case, it makes for an easy insertion of a point to break into the debugger.

Also, as mentioned by Mark Lutz in the Learning Python Book, it is technically legal (although unnecessary and annoying) to terminate all your statements with semicolons.

Create an in-memory DIV

$("<div/>");

Add click handlers, styles etc - and finally insert into DOM into a target element selector:

$("<div/>", {_x000D_
_x000D_
  // PROPERTIES HERE_x000D_
  _x000D_
  text: "Click me",_x000D_
  id: "example",_x000D_
  "class": "myDiv",      // ('class' is still better in quotes)_x000D_
  css: {           _x000D_
    color: "red",_x000D_
    fontSize: "3em",_x000D_
    cursor: "pointer"_x000D_
  },_x000D_
  on: {_x000D_
    mouseenter: function() {_x000D_
      console.log("PLEASE... "+ $(this).text());_x000D_
    },_x000D_
    click: function() {_x000D_
      console.log("Hy! My ID is: "+ this.id);_x000D_
    }_x000D_
  },_x000D_
  append: "<i>!!</i>",_x000D_
  appendTo: "body"      // Finally, append to any selector_x000D_
  _x000D_
}); // << no need to do anything here as we defined the properties internally.

_{Similar to ian's answer, but I found no example that properly addresses the use of methods within the properties object declaration so there you go.}

Use overrideLibrary when the minSdk is declared in build.gradle instead of in AndroidManifest.xml

If you are using Android Studio:

add <uses-sdk tools:overrideLibrary="android.support.v17.leanback"/> to your manifest, don't forget to include xmlns:tools="http://schemas.android.com/tools" too.

I had the same question for macOS.

But the root cause was not installing Six. My macOS shipped Python version 2.7 was being usurped by a Python2 version I inherited by installing a package via brew.

I fixed my issue with: $ brew uninstall python@2

Some context on here: https://bugs.swift.org/browse/SR-1061

Starting server and publishing without any projects helped me to modify the "Server Locations".

Also works fine within a class:

def update_property(self, property, value):
   setattr(self, property, value)

Actually speaking, when I tried this, it worked only when I set the action and method value for the form. Funny how it works though!

DECLARE @test nvarchar(100)

SET @test = 'Foreign Tax Credit - 1997'

SELECT @test, left(@test, charindex('-', @test) - 2) AS LeftString,
    right(@test, len(@test) - charindex('-', @test) - 1)  AS RightString

If you're using jQuery, here's a nice simple method

$("#dateField").val(new Date().toISOString().substring(0, 10));

Or there's the old traditional way:

document.getElementById("dateField").value = new Date().toISOString().substring(0, 10)

I realize this is a pretty old question, however I am using an html multiple file selection upload to queue any number of files which can be selectively removed in a custom UI before submitting.

Save files in a variable like this:

let uploadedFiles = [];

//inside DOM file select "onChange" event
let selected = e.target.files[0] ? e.target.files : [];
uploadedFiles = [...uploadedFiles , ...selected ];
createElements();

Create UI with "remove a file":

function createElements(){
  uploadedFiles.forEach((f,i) => {

    //remove DOM elements and re-create them here
    /* //you can show an image like this:
    *  let reader = new FileReader();
    *  reader.onload = function (e) {
    *    let url = e.target.result;
    *    // create <img src=url />
    *  };
    *  reader.readAsDataURL(f);
    */

    element.addEventListener("click", function () {
      uploadedFiles.splice(i, 1);
      createElements();
    });

  }
}

Submit to server:

let fd = new FormData();
uploadedFiles.forEach((f, i) => {
  fd.append("files[]", f);
});
fetch("yourEndpoint", { 
  method: "POST", 
  body: fd, 
  headers: { 
    //do not set Content-Type 
  } 
}).then(...)

Can also use:

find . -mindepth 1 -mtime +3 -delete

To not delete target directory

Use the following lines of codes and you will find the solution...

pictureBox1.ImageLocation = @"C:\Users\Desktop\mypicture.jpg";
pictureBox1.SizeMode =PictureBoxSizeMode.StretchImage;

If it is in RelativeLayout you can use android:layout_toRightOf="@id/<id_of_desired_item>"

Or

If you want to align to the right corner of the device the place android:layout_alignParentRight="true"

You can use varargs for optional parameters:

public class Booyah {
    public static void main(String[] args) {
        woohoo(1);
        woohoo(2, 3);
    }
    static void woohoo(int required, Integer... optional) {
        Integer lala;
        if (optional.length == 1) {
            lala = optional[0];
        } else {
            lala = 2;
        }
        System.out.println(required + lala);
    }
}

Also it's important to note the use of Integer over int. Integer is a wrapper around the primitive int, which allows one to make comparisons with null as necessary.

If you want to ditch empty strings in the array.

["Jet", "Fire"].filter { !$0.isEmpty }.joined(separator: "-")

If you want to filter nil values as well:

["Jet", nil, "", "Fire"].flatMap { $0 }.filter { !$0.isEmpty }.joined(separator: "-")

if (value == "") {
  // it is empty
}

Guid.NewGuid(), as it creates GUIDs as intended.

Guid.NewGuid() creates an empty Guid object, initializes it by calling CoCreateGuid and returns the object.

new Guid() merely creates an empty GUID (all zeros, I think).

I guess they had to make the constructor public as Guid is a struct.

Here is an async helper function written in typescript that seems to do the trick for me. I guess this will not work for long-lived processes but still might be handy for someone?

import * as child_process from "child_process";

private async spawn(command: string, args: string[]): Promise<{code: number | null, result: string}> {
    return new Promise((resolve, reject) => {
        const spawn = child_process.spawn(command, args)
        let result: string
        spawn.stdout.on('data', (data: any) => {
            if (result) {
                reject(Error('Helper function does not work for long lived proccess'))
            }
            result = data.toString()
        })
        spawn.stderr.on('data', (error: any) => {
            reject(Error(error.toString()))
        })
        spawn.on('exit', code => {
            resolve({code, result})
        })
    })
}

With Javascript SDK, you can change the code as below, this should be added after FB.init call.

     // Additional initialization code such as adding Event Listeners goes here
FB.getLoginStatus(function(response) {
      if (response.status === 'connected') {
        // the user is logged in and has authenticated your
        // app, and response.authResponse supplies
        // the user's ID, a valid access token, a signed
        // request, and the time the access token 
        // and signed request each expire
        var uid = response.authResponse.userID;
        var accessToken = response.authResponse.accessToken;
        alert('we are fine');
      } else if (response.status === 'not_authorized') {
        // the user is logged in to Facebook, 
        // but has not authenticated your app
        alert('please like us');
         $("#container_notlike").show();
      } else {
        // the user isn't logged in to Facebook.
        alert('please login');
      }
     });

FB.Event.subscribe('edge.create',
function(response) {
    alert('You liked the URL: ' + response);
      $("#container_like").show();
}

Have you considered reading a book on PHP security? Highly recommended.

I have had much success with the following method for non SSL certified sites.

1. Dis-allow multiple sessions under the same account, making sure you aren't checking this solely by IP address. Rather check by token generated upon login which is stored with the users session in the database, as well as IP address, HTTP_USER_AGENT and so forth

2. Using Relation based hyperlinks Generates a link ( eg. http://example.com/secure.php?token=2349df98sdf98a9asdf8fas98df8 ) The link is appended with a x-BYTE ( preferred size ) random salted MD5 string, upon page redirection the randomly generated token corresponds to a requested page.

   • Upon reload, several checks are done.
   • Originating IP Address
   • HTTP_USER_AGENT
   • Session Token
   • you get the point.

3. Short Life-span session authentication cookie. as posted above, a cookie containing a secure string, which is one of the direct references to the sessions validity is a good idea. Make it expire every x Minutes, reissuing that token, and re-syncing the session with the new Data. If any mis-matches in the data, either log the user out, or having them re-authenticate their session.

I am in no means an expert on the subject, I'v had a bit of experience in this particular topic, hope some of this helps anyone out there.

I also came across this problem. In my case, I didn't know the type of the IEnumerable. So the answers given above wont work. However, I solved it like this:

public static DataTable CreateDataTable(IEnumerable source)
    {
        var table = new DataTable();
        int index = 0;
        var properties = new List<PropertyInfo>();
        foreach (var obj in source)
        {
            if (index == 0)
            {
                foreach (var property in obj.GetType().GetProperties())
                {
                    if (Nullable.GetUnderlyingType(property.PropertyType) != null)
                    {
                        continue;
                    }
                    properties.Add(property);
                    table.Columns.Add(new DataColumn(property.Name, property.PropertyType));
                }
            }
            object[] values = new object[properties.Count];
            for (int i = 0; i < properties.Count; i++)
            {
                values[i] = properties[i].GetValue(obj);
            }
            table.Rows.Add(values);
            index++;
        }
        return table;
    }

Keep in mind that using this method, requires at least one item in the IEnumerable. If that's not the case, the DataTable wont create any columns.

Another option is to install anaconda, which comes with packages such as: Matplotlib, numpy and pandas.

The modern answer:

if your app support split view on iPad, this problem becomes a little complicated. You need window's size, not the screen's, which may contain 2 apps. Window's size may also vary while running.

Use app's main window's size:

UIApplication.shared.delegate?.window??.bounds.size ?? .zero

Note: The method above may get wrong value before window becoming key window when starting up. if you only need width, method below is very recommended:

UIApplication.shared.statusBarFrame.width

The old solution using UIScreen.main.bounds will return the device's bounds. If your app running in split view mode, it get the wrong dimensions.

self.view.window in the hottest answer may get wrong size when app contains 2 or more windows and the window have small size.

While unzipping will reveal the resources, the AndroidManifest.xml will be encoded. apktool can – among lots of other things – also decode this file.

To decode the application App.apk into the folder App, run

apktool decode App.apk App

apktool is not included in the official Android SDK, but available using most packet repositories.

I tried the following and it works for me better

Code:

.unstyled-link{ 
  color: inherit;
  text-decoration: inherit;
  &:link,
  &:hover {
    color: inherit;
    text-decoration: inherit;
  }
}

$_GET contains the keys / values that are passed to your script in the URL.

If you have the following URL :

http://www.example.com/test.php?a=10&b=plop

Then $_GET will contain :

array
  'a' => string '10' (length=2)
  'b' => string 'plop' (length=4)

Of course, as $_GET is not read-only, you could also set some values from your PHP code, if needed :

$_GET['my_value'] = 'test';

But this doesn't seem like good practice, as $_GET is supposed to contain data from the URL requested by the client.

To answer the question of going from an existing python datetime to a pandas Timestamp do the following:

    import time, calendar, pandas as pd
    from datetime import datetime
    
    def to_posix_ts(d: datetime, utc:bool=True) -> float:
        tt=d.timetuple()
        return (calendar.timegm(tt) if utc else time.mktime(tt)) + round(d.microsecond/1000000, 0)
    
    def pd_timestamp_from_datetime(d: datetime) -> pd.Timestamp:
        return pd.to_datetime(to_posix_ts(d), unit='s')
    
    dt = pd_timestamp_from_datetime(datetime.now())
    print('({}) {}'.format(type(dt), dt))

Output:

(<class 'pandas._libs.tslibs.timestamps.Timestamp'>) 2020-09-05 23:38:55

I was hoping for a more elegant way to do this but the to_posix_ts is already in my standard tool chain so I'm moving on.

Please find below the code that generates automatically the content of the txt local file and display it html. Good luck!

<html>
<head>
  <meta charset="utf-8">
  <script type="text/javascript">

  var x;
  if(navigator.appName.search('Microsoft')>-1) { x = new ActiveXObject('MSXML2.XMLHTTP'); }
  else { x = new XMLHttpRequest(); }

  function getdata() {
    x.open('get', 'data1.txt', true); 
    x.onreadystatechange= showdata;
    x.send(null);
  }

  function showdata() {
    if(x.readyState==4) {
      var el = document.getElementById('content');
      el.innerHTML = x.responseText;
    }
  }

  </script>
</head>
<body onload="getdata();showdata();">

  <div id="content"></div>

</body>
</html>

Set a value to 'name' property in initial state.

this.state={ name:''};

The break keyword does exactly that. Here is a contrived example:

public static void main(String[] args) {
  int i = 0;
  while (i++ < 10) {
    if (i == 5) break;
  }
  System.out.println(i); //prints 5
}

If you were actually using nested loops, you would be able to use labels.

You can use Split():

import java.io.*;

public class Splitting
{

    public static void main(String args[])
    {
        String Str = new String("004-034556");
        String[] SplittoArray = Str.split("-");
        String string1 = SplittoArray[0];
        String string2 = SplittoArray[1];
    }
}

Else, you can use StringTokenizer:

import java.util.*;
public class Splitting
{
    public static void main(String[] args)
    {
        StringTokenizer Str = new StringTokenizer("004-034556");
        String string1 = Str.nextToken("-");
        String string2 = Str.nextToken("-");
    }
}

In C# you can loop through the array printing each element. Note that System.Object defines a method ToString(). Any given type that derives from System.Object() can override that.

Returns a string that represents the current object.

http://msdn.microsoft.com/en-us/library/system.object.tostring.aspx

By default the full type name of the object will be printed, though many built-in types override that default to print a more meaningful result. You can override ToString() in your own objects to provide meaningful output.

foreach (var item in myArray)
{
    Console.WriteLine(item.ToString()); // Assumes a console application
}

If you had your own class Foo, you could override ToString() like:

public class Foo
{
    public override string ToString()
    {
        return "This is a formatted specific for the class Foo.";
    }
}

On Linux, give read/write permissions to the entire folder containing the database file.

Also, SELinux might be blocking the write. You need to set the correct permissions.

In my SELinux Management GUI (on Fedora 19), I checked the box on the line labelled httpd_unified (Unify HTTPD handling of all content files), and I was good to go.

This worked for me in Kotlin class

fun hideKeyboard(activity: Activity) {
    try {
        val inputManager = activity
            .getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
        val currentFocusedView = activity.currentFocus
        if (currentFocusedView != null) {
            inputManager.hideSoftInputFromWindow(currentFocusedView.windowToken, InputMethodManager.HIDE_NOT_ALWAYS)
        }
    } catch (e: Exception) {
        e.printStackTrace()
    }

}

Be careful when using Application.Transpose with a huge number of values. If you transpose values to a column, excel will assume you are assuming you transposed them from rows.

Max Column Limit < Max Row Limit, and it will only display the first (Max Column Limit) values, and anithing after that will be "N/A"

fileinput seems to be for multiple input streams. This is what I would do:

with open("test.txt") as file:
    for line in file:
        line = line.rstrip()
        if line:
            print(line)
